BICYCLE-STAN D.

SPECIFICATION forming part of Letters Patent No. 487,473, dated December6, 1892.

Application filed July '7, 1892. Serial No. 439,309. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE S. CROSBY, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Bicycle-Stands, of which thefollowing is a specification.

' This invention relates to the stands or supports which are used forholding bicycles in an upright position when not in use.

One of the objects of my invention is to produce an efficient standwhich will reliably support the bicycle and at the same time permit thesame to be moved into any desired position without detaching it from thestand.

The invention has the further object to provide the stand with aconvenient clamp or locking device which is readily attached to the stepor similar projection of the machine and which will accommodate steps ofdifierent forms and sizes, so that the stand may be used in connectionwith bicycles of various styles.

In the accompanying drawings, Figure l is a side elevation of abicyclesupported by my improved stand. Fig. 2 is a side elevation of the standon an enlarged scale. Fig. 3 is an elevation thereof at right angles toFig. 2. Fig. 4. is a sectional elevation of the stand. Fig. 5 is a topplan view thereof on a further enlarged scale.

Like letters of reference refer to like parts in the several figures.

A represents the base of the stand, which is secured to the floor byscrews or or other means, and B is a hollow post or standard attached tosaid base. The latter is provided with an internally-screw-threadedsocket a, with which the externally-threaded lower end of the hollowstandard engages.

C is a supporting-rod telescoping into the hollow standard, and which ismade vertically adjustable in the same by a collar or stop d, adjustablysecured to the supporting-rod and resting loosely upon the upper end ofthe standard. This collar is secured to the supporting-rod by a clampingor set screw e, arranged in a threaded opening in the collar and bearingwith its inner end against the rod. Upon loosening this set screw thecollar may be adjusted vertically on the supporting-rod, so as tosupport the rod at any desired elevation on the standard,the set-screwof the collar being again tightened after adjusting the collar on therod. The supporting-rod carries at its upper end a clamp or lockingdevice, which is adapted to engage with the step f or similar projection of the frame of the bicycle. This clamp is preferably constructedas follows: 9 is a lower horizontal clamping-jaw secured to the upperend of the supportingrod 0 and adapted-to bear against the under side ofthe bicycle-step or other projection. h is an upper clamping-jaw pivotedat one end to one end of the stationary lower jaw g by a horizontalpivot and adapted to bear against the upperside of the step. Thejawsgand hare preferably provided in their inner faces with seats ordepressions for the step, as shown in Figs. 2 and 4. I is a yoke pivotedat its inner end to the stationary jaw g opposite the outer end of thehinged jaw h and composed of links or side bars arranged on oppositesides of the hinged jaw and connected at their outer ends bya cross-bar2'. J is aclamping-screw arranged in a threaded opening in the cross-bari and bearing with its inner end against the adjacent upper side of thehinged jaw, thereby clamping the jaw against the step or otherprojection of the bicycle and securely holding the same in the clamp.The

screw J is provided with a hand-wheel for turning it.

In attaching the bicycle to the stand the clamp of the stand is openedby loosening the clamping-screw J and swinging the yoke I downward intothe position shown by dotted lines in Fig. 2, so as to release thehinged jaw h. The bicycle is then placed adjacent to the stand with itsstep resting upon the lower jaw g of the clamp, and the hinged jaw isswung over the step, after which the yoke is swung upward into theposition shown by full lines and its clamping-screw tightened againstthe hinged jaw. The step is thus firmly held in the clamp and thebicycle is reliably supported in an upright position. The yoke I and itsclamping-screw permit of a considerable range of movement of the hingedjaw toward and from the stationary jaw, which enables the clamp toreceivesteps of different sizes and renders the stand applicable tobicyles of different manufacture. Asthe supporting-rod C is not clampedin the standard, but is supportedtherein by the stop or collar (1, whichrests loosely upon the upper end of the standard, it is free to turn inthe latter, thus permitting the bicycle to be turned into any desiredposition without detaching it from the stand. This feature is especiallydesirable in cleaning the machine, as it enables it to be placed in themost convenient position. It also renders the stand very useful inbicycle-warerooms', as it permits the machines to be moved out of theway in cleaning the rooms andto be again returned to theirplaces withoutdetaching them from their stands or disturbing the latter.-

It is obvious that the bicycle may be attached to the stand by means ofone of the foot-rests arranged on the front fork of the frame,- as shownby dotted lines in Fig. 1, instead of by means of the step.

I claim as my invention 1. A bicycle-stand consisting of a post orstandard and a support adapted to be attached to the bicycle and capableof turning on said post or standard, substantially as set forth. I j A2. A bicycle-stand consisting of a hollow post or standard and asupporting-rod adapted to be attached to the bicycle, capable of turningin said standard and provided with acollar or stop whereby the same issupported in the standard, substantially as set forth.

3. A bicycle-stand consisting of a hollow standard, a supporting-rodarranged in said standard and capable of turning therein, and a collaror stop adjustably secured to said rod and resting u on the standard,substantially as set forth.

4. A bicycle-stand consisting of a hollow standard and a supporting-rodcapable of turning in said standard and provided with an adjustable stopor collar resting on the standard and a clamp or locking device forattaching it to the step or similar projection of a bicycle,substantially as set forth.

5. In abicycle-stand,thecombination,witl1 1 a hollow standard, of asupporting-rod arranged in said standard and provided with an adjustablestopor collar whereby it is supported on the standard and a clampingdevice carried by the support-ing-r'od and composed of astationary jawsecured to the upper end of the supporting-rod, a jaw hinged at one endto the stationary jaw, a yoke pivoted to the opposite end of thestationary jaw and embracing the free end of the hinged jaw, andaclamping-screw carried by said yoke and bearing against the hinged jaw,substantially as set forth. 4 l
